Raj plastic industries presents polypropylene ball valves, made from polypropylene material, which is chemically inert, having durability and more strength. It is corrosion free and chemical resistant to organic solvents, acids, alkalis and salt-water solutions. Smooth interior surfaces of valve compared to metal valve assure low friction loss and high flow rates. The various advantages of ball valves include easy installation and maintenance free, low thermal conductivity and good electrical insulation.
